Notes: Estimated pressure calculated as total depth (water + sediment; m) x 0.01015 MPa/m. Estimated temperature calculated as sediment depth (m) x 0.058°C/m + 4.4°C. Hydrate temperature calculated from CSMHYD (Sloan, 1998) using gas composition, pressure, and 3.5% NaCl salinity. Depth for hydrate temperature calculated using temperature from CSMHYD and depth (m) = (T – 4.4°C)/0.058°C/m. Hydrate structure determined by calculations from CSMHYD (Sloan, 1998).
